As a seller, how can I prove that I've sent the item to the buyer?
If you are a seller, one way to show proof is to use a carrier with online tracking. For transactions involving merchandise worth up to the coverage amount (or the equivalent in the currency of the transaction) or more, please also keep an online receipt with the recipient’s signature as proof of delivery.
